Specification of Letters Patent.

Patented Nov. 28, 1911.

Application filed January `17, 1911. Serial No. 603,062.

To all whom 'it' may concemr l l Be it known that I, FRANK W7. DoMALsKI,a citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Reservoir-Brushes, of which the following is aspecification.

M y invention relates to magazine or reservoir brushes, and has foroneof its objects to generally improve the construction of brushes ofthe type to which the invention relates.

Other and further objects of the invention will readily become apparentto persons skilled in the art from a consideration of the specificationtaken in conjunction with the drawings, wherein- Figure 1 is alongitudinal central section of the device; Fig. 2 is a transversesection taken on line 2 2 of Fig. 1, showing the )referred form' FiO. 3is a similar view* taken on line 8-3 of Fig. 1; Fig.v 4e is an enlargedtop plan view of the fiat back brush proper, showing the attaching meanssecured to the brush back; and F ig. 5 is a crosssectional view of amodificati on, showing the brush back to be semi-circular incross-section.

ln all of the views the same reference characters refer always tosimilar parts.

My brush consists essentially of two principal parts, the brush proper 5and the reservoir 'or magazine (3. intended to contain substances suchas soap, cocoa butter, or the like, which is to be applied' anddistributed by the bristles of the brush. The reservoir 7 is preferablymade of a sheet metal cap closed at one end and screwethreaded, as at 8,at its open end, to receive a screw-threaded closure 9. The closure isprovided with a central perforation through which a screw-threaded feedrod 10 passes. A piston, 11, carries a screwthreaded nut, 12, whichmakes threaded engagement with the feed' rod 10. The rod carries a thumbkey or button 13, secured therein as by pin 14, by which said rod may berotated. A collar 15 is secured as by pin 16 to the rod so that the rodmay not be withdrawn through the perforation in the closure. The rod andnut are preferably provided with left-handed screw-threads, so that whenthe key or button 13 is turned to The reservoir is l the right,thekpiston 11 will be moved to- Ward the closed end of the reservoir. Inorder that the piston may be given a longitudinal movement, within saidreservoir when the screw is rotated, some means mustbe provided toprevent the piston from being rotated with the screw rod. To this end, Iprefer to crimp the tube 7 longitudinally and thereby to provide a bead,as 17 extending inwardly of the tube or receptacle and substantially thefull length thereof, to form a. piston guide. I cut a notch 1S 'in oneedge of the piston, of such size as to permit easy free longitudinalmovement of the piston wit-hin said receptacle and which will at thesame time prevent the rotation of the piston. The external groove 19,vwithin the bead 17, from the rear end of the reservoir to a point nearthe center thereof, by the cooperation of the wall 20, ,forms a conduitto convey the material from the receptacle 7 through the opening 21 tothe terminal opening 22, which latter is located in the midst of thetufts of bristles of the brush. 1

It is now clearly apparent that if the receptaole 7 be filled with amaterial, such as relatively soft soap or the-like, and the button 13 beturned to the right, that the piston will be, thereby, moved'toward theclosed end of the receptacle and a corresponding quantity of suchmaterial will be thus eX- pressed from said reservoir and will bedelivered through the conduit 20 to the bristles to be by themdistributed, as in common use of brushes.

It is desirable to detachably secure the brush and reservoir so that newparts may be supplied without the necessity of renewing the entirestructure.

To the lower portion of the tube 7 I se cure a sheet metal basestructure 24 having a flat base part 25, perforated at intervals toreceive the coperating fastening members which are secured to the uppersurface of the brush back 26. These members are in the form of springstuds 27 located on, and secured to. the brush back, so that they willregister with the attaching perforations made in the flat base part 25.To apply the reservoir to the brush it is only necessary to place theparts in proper position and press them together until` the resilienthead ed studs 217 pass through the respective perforations. To separatethe parts it is only necessary to pull them apart.

The brush 5 is composed of a fiat back 26, provided With the usualassemblage of tufts of bristles 28, secured in the usual manner toprovide a flat bristle surface.

There are conditions when a brush, having a circular bristle surface, isdesirable, in Which case a curved part 26 having bristles 28 securedthereto, and having correspondingly curved surfaces may be employed,instead of the Hat brush structure, in which event, longitudinal grooves30-30 should be made in the back 26 and corresponding beads 3L-3l shouldbe secured to the sides of the receptacle 7, so that the reservoir tube"may be slid into the curved bristle-carrying structure as a means fordetachably securing the parts together.

When it is desirable to fill the receptacle, the piston and feed rod maybe removed therefrom by detaching the closure 9, which may be secured inplace by a screw-thread means, bayonet-joint, or otherwise, and byreplacing same after filling, the device is again ready for use.

My improved brush may be used Where soap and like material are to beapplied by a brushsuch as in scrubbing floors, Washing rugs, or carpets,or for the application of other substances in massage manipulation andthe like, in which latter event the form shown in Fig. 5 is preferable.

I have herein described an embodiment of my invention Without anyattempt to disclose the many variations that may be made therefromWithin ordinary skill Within the scope of the claims.

lVhat I claim is:

l. In a device of the character described, a tubular reservoir and anelongated brush, eyelets and cooperative spring studs carried by therespective parts for detachably securing said parts together, and meansfor feeding material from said reservoir through the back of the brushinto the bristles thereof.

2. In a device of the character described, a brush comprising a back andbristles secured therein, a tubular reservoir detachably securedlongitudinally to said back, a conduit from said reservoir extendingalong the under side thereof and projecting through said back into thebristle space, said conduit located 'longitudinally between saidreservoir and back, a piston Within said reservoir, and means for movingsaid pis- 'ton to express the contents of said reservoir into saidbristle space.

3. In a device of the character described, a brush, and a cylindricalreservoir of substantially equal length, detachably attach-l able inlongitudinal relation, spring studs secured to one member, the othermember provided With registering perforations for coperation With saidstuds as means of fastening, whereby pressing the parts together securesthem in substantial relation.

4t. In a device of the character described, an elongated cylindricalreservoir closed at one end and provided With a longitudinal crimp inthe Walls thereof to form an internal piston-guiding bead and anexterior groove, a piston Within said cylinder provided With a notchoverlying said bead, a rotary means for moving said pistonlongitudinally of the cylinder toward and from the closed end, and aconduit formed in part by said exterior groove communicating With theclosed end of said cylinder, at one end, and provided With a right angledelivery spout extending into the midst of the bristles at the otherend.

In testimony whereof I hereunto set my hand in the presence of tvvoWitnesses.
